It can be challenging when you can't install the latest update, jndiwjdwd. I'm here to help you resolve this.

I appreciate you for performing some troubleshooting steps to fix the error.

There are several reasons that cause QuickBooks to require a reboot, and I've listed them below:

• Corrupted or Damaged Hard Disk
• Damaged or missing QBWUSER.INI file
• A lengthy Company Name
• Wrong Installation of QuickBooks Desktop
• Old an outdated operating system

To fix this, make sure to access an administrator account to resolve this problem. Then, take the methods that are listed below to fix the error:

1. You have to log in to Windows using your administrative account.
2. Go to the Start menu, then select the Control Panel, and click on Programs.
3. Choose to turn Windows features on or off.
4. Next, you have to turn on .NET Framework 3.5.
5. After that, reboot your system.

Then, install the QuickBooks update again. Here's how:

1. Go to Help and select Update QuickBooks Desktop.
2. Hit Update Now, then Get Updates.
3. Close and reopen QuickBooks to install the update again.
   

If the issue persists, I recommend uninstalling the Microsoft Visual C++. Then, reinstall the Visual C++ for 2008, 2010, 2013, 2015, and 2017. Once done, update the program again. To do so, please follow the steps above.
